1) Fe2O3 + 6HCl => 2FeCl3 + 3H2O
FeCl3 + 3NaOH => Fe(OH)3 + 3NaCl
2Fe(OH)3 => Fe2O3 + 3H2O
2) BaO + 2HCl => BaCl2 + H2O
BaO + H2O => Ba(OH)2
Ba(OH)2 + 2HCl => BaCl2 + 2H2O
Fe2O3 + 6HCl >>> 2FeCl3 + 3H2O
FeCl3 + 3NaOH >>> Fe(OH)3 + 3NaCl
2Fe(OH)3 >>> Fe2O3 + 3H2O
BaO + 2HCl >>> BaCl2 + H2O
BaO + H2O >>> Ba(OH)2
Ba(OH)2 + 2HCl >>> BaCl2 + 2H2O
